1. A method for generating encrypted messages that are used to authenticate a tracking device by an authentication device, the method comprising:
obtaining, by an encryption module of a tracking device, a device identifier that uniquely identifies the tracking device;
generating, by the encryption module, an obscured device identifier by modifying the device identifier based on a secret pattern, wherein the device identifier is obscured by inserting a random N-bit string in the device identifier based on bit positions indicated by the secret pattern;
generating, by the encryption module, a message based on the obscured device identifier;
encrypting, by the encryption module, the message using a secret key to obtain an encrypted message;
outputting, by the encryption module, the encrypted message to a transmission module of the tracking device; and
modulating, by the transmission module, a response signal that includes the encrypted message for transmission via an antenna of the tracking device.
